I never said that it was state of the art or "the" leading, my point is Go GC is currently a good all-arround GC, and I've read that article, I think the author is bias against Go and currently there is no article even proving that the 2 new Java GC are faster than the Go one. ( or even faster than G1 )

You know when you end your article with "Overall, it looks to me like the Java guys are winning the low latency game." when none of those GC are actually production ready ... Go GC low latency has been stable and used for some time now.

Out of the box Go GC is very good and doesn't need all the memory or the tunning from G1. ( I spend years tunning GC for Java application it's a nightmare )
